Deep Pours up to 5cm: Choosing the Right Epoxy Resin

Q: Best Practices for a Flawless Deep Pour

Layering for Large Projects: For projects exceeding 100cm per side or over 8kg total weight, pour in sequential layers (up to 5cm each) and allow 6–8 hours between pours. This prevents overheating and ensures a thorough cure. Accurate Mixing: Always follow the recommended mixing ratio by weight or volume for your chosen resin to achieve optimal results. EpoxyTable 5-Five, for example, uses a 100:55 (resin to hardener) ratio by weight. Environmental Conditions: Pour resin in a controlled environment with stable temperature and humidity to reduce risks of bubbles or surface imperfections.

Deep Pours Up to 5cm: Best Practices for Epoxy Resin Casting

Deep pour epoxy projects, such as tables or river-style castings, require resins specifically designed for thicker layers to ensure a strong and flawless result. If you plan to pour layers up to 5cm, it’s important to choose the right materials and follow key preparation steps to prevent hardening problems.

Selecting an Epoxy Resin Suitable for Deep Pours

Not all epoxies can safely be poured in thick layers without overheating or improper curing. For pours up to 5cm, choose a resin formulated for deep casting, such as EpoxyTable 5-Five. This resin is designed to be poured in layers up to 5cm thanks to its low exothermic reaction, minimising the risk of cracking or incomplete hardening. For even thicker layers, “Epoxytable 10-Ten” may be suitable when used with layering techniques.

When Deep Pour Guidance Matters Most

If you are working on statement tables, large castings, or any project where the resin layer is over 2cm and up to 5cm thick, correct resin choice and technique will noticeably reduce the risk of soft spots or persistent tackiness. Deep pour guidance is crucial for reliability and professional-quality results, especially in furniture and art pieces.
